What equipment is needed to set up a small laboratory?
Thread Content
We operate a small coal yard that mixes coal of various specifications, and we want to set up our own laboratory. Currently, coking coal is the main material used for blending, and the parameters that need to be measured include moisture, ash content, volatile matter, sulfur content, G value, and Y value. What equipment is needed to measure the above indicators? In the future, thermal coal and injection coal will also need to be mixed in; what equipment is required for this, and which parameters need to be measured? I would appreciate some guidance from those with more experience.
Coal quality analysis instruments generally include: industrial coal analyzers, coal moisture meters, ash melting point testers, ash volatility detectors, coal hydrogen analyzers, coal hydrogen content analyzers, coal calorimeters, coal sulfur analyzers, coal ignition point testers, coal caking tendency testers, coal activity testers, and so on. These are the devices that we generally use for coal quality analysis. Coal quality industrial analyzer: It allows for the measurement of moisture, ash content, and volatile matter in a sample all at once, using a single device. An advanced analytical instrument for determining high calorific value and low calorific value. Industrial coal analysis is primarily used in coal production and mining, as well as in commercial sectors and various users of coal, such as coking plants, power plants, chemical plants, etc. Moisture meter: Particularly suitable for determining the total moisture content of coal, as well as the moisture content of coal samples dried in Mt or air, namely Mad (analytical water). It can also be used to measure the moisture content of other non-metallic substances. Coal moisture meters are primarily used in all industries where it is necessary to determine moisture content. Ash fusion point tester: A coal ash fusion point detector is an instrument used to measure the melting properties of coal. This instrument uses a silicon-carbon tube as the heating element, with a thyristor voltage regulator to control the temperature. With slight modifications, this instrument can be used to determine the carbon dioxide activity of coal and for other heat treatment processes. This instrument can be widely applied in industries such as electricity, coal, cement, and metallurgy. Ash volatilization analyzer: The ash volatilization analyzer is a specialized device used to determine the ash content. This instrument features advantages such as speed, accuracy, efficiency, and energy conservation, and is widely used in laboratories across industries including coal, geology, metallurgy, power generation, chemicals, and foreign trade. Coal hydrogen analyzer: It is primarily used to determine the hydrogen content in both organic and inorganic components of coal and other solid materials. It is an essential instrument in laboratories in industries such as coal processing, power generation, and metallurgy; it is also widely used in organizations in the chemical industry and quality inspection sectors. Coal hydrogen analyzer: The hydrogen analyzer is suitable for determining the contents of carbon and hydrogen in coal and other organic substances. The sample under test is burned in an oxygen stream at high temperatures to produce water and carbon dioxide, which are then absorbed by a water absorbent and a carbon dioxide absorbent respectively; the percentage contents of carbon and hydrogen are calculated based on the increase in weight of the absorbents. It can be used in laboratories in sectors such as coal, chemicals, metallurgy, power generation, and geological exploration. Coal calorimeter: It is mainly used to determine the calorific value of solid combustibles such as coal, coke, and gangue, in order to assess the quality of the materials being tested. It is a major instrument in coal quality laboratories and is widely used in industries such as electricity, coal, metallurgy, petrochemicals, quality inspection, and environmental protection. Coal sulfur analyzer: Used to determine the total sulfur content in combustible materials such as coal, coke, and gangue. It is used to measure the quality of the material under test, and is an essential instrument in laboratories in industries such as coal, electricity, chemicals, and metallurgy. Coal ignition point tester: It is used to determine the ignition temperature of coal. By measuring this temperature, preventive measures can be taken to avoid pollution and economic losses caused by spontaneous combustion of coal. It plays an important role in production, research, and application sectors. Coal caking index tester: Mainly used to determine the ease of caking of coal during gasification or combustion. It is widely used in laboratories in industries such as coal, metallurgy, and power generation, especially in units that use coal as fuel, such as boiler plants. It enables the preliminary determination of sludging tendency, thereby helping to guide the selection of appropriate coal types on-site and preventing sludging.
Moisture (total water, internal water): 3 to 4 adjustable electric heating convection ovens, along with several enamel trays and a few galvanized shallow trays are sufficient for this purpose. Ash, volatilization, caking – 3 muffle furnaces are required, along with several ash dishes, a crucible holder equipped with covered caking crucibles, and clamps. Coulomb sulfur analyzer, porcelain boat, gel layer analyzer. I can do all of the above; as for coal injection using thermal coal, my current knowledge isn’t sufficient for that
